In these scenarios, one way of implementing services uses web service architecture. So it is important to study how these mobile devices will integrate efficiently to access web services. Because of the reduced capabilities of the mobile devices, their access to web services is not easy and might have some performance costs related to show data speeds and processing both HTTP commands and XML. Moreover, some mobile devices could not support web service access and if supported it lacks of web service search engine. In order to allow mobile devices to access web services efficiently, giving a solution to the previous problems, we propose a new architecture based on a peer-to-peer with distributed hash tables network, as a gateway between the mobile device and web service. This architecture is a base software simulator for an Ambient Network environment developed in our research group. Nodes of the peer-to- peer network publish services, allow finding them easily and acting as a gateway to the mobile devices for accessing web services more efficiently.</p>
